Why the modern economy is fighting against your biology.

What is the compelling argument for circadian health that the economy has not yet been forced to hear? I think that in the last century, with the arrival of artificial light, you can see people drifting away from their normal, natural behavior — because they aren't really aware that they shouldn't. They don't experience it as unhealthy, because it's a very small, gradual difference.

So I think the compelling argument is simply to listen to your body, and to listen to nature — to biodiversity — and recognize that things have a certain rhythm that you should respect.
